Frequently Asked Questions
How long does it take for a clock to receive a signal?
If everything is installed correctly and the transceiver is open, the clock should get the signal within a few
minutes. Once the clock has been synchronized, it will attempt to acquire a time signal once every minute.
When I power my clock, it seems to be running a test instead of showing the time. What is
it doing?
Immediately after power up an SBL/SBLG will run an LED display test to allow the user to confirm that each
segment of the display is functioning properly.
How can I determine that the clock is receiving a signal?
if the clock is not receiving a signal, then the colons on the clock will blink on and off, unless configured by
the user not to do so. This option is controlled through either the Manual Controls; Setting 13.
The clock is not powered. What do I do?
1. Measure the input voltage to the clock. The voltage should match one of the corresponding
ranges below, depending on the digit size and power source:
2.5” Digit size 4.0” Digit size
24V 11-28 V 16-28 V
110VAC 85-130 VAC 100-130 VAC
230VAC 180-260 VAC 200-260 VAC
2. Make sure that the transformer is an isolated transformer if using a 24VAC model.
3. Make sure the ground wire is not touching other wires.
NOTE: If you fail to follow instructions 2 and 3 listed above, the fuses can be blown.
The clock is in a location with a poor/no signal. What should I do?
If the clock is in a location that isn’t receiving signal, or is not receiving a strong-enough signal to
synchronize, install a signal repeater or add more secondary clocks in a location between clocks that are
receiving the signal and clocks that are not.
